Amniotic Band Sequence

Amniotic band sequence is a developmental disorder during pregnancy in which fibers detached from the amniotic sac wrap around parts of the fetus, potentially affecting fingers, limbs, or other body structures.

How does it present? its effects vary widely from case to case: from grooves or constrictions on a finger to more marked differences in hands, feet, or limbs, depending on where and how intensely the bands act.

When is it identified? it is usually detected on pregnancy ultrasounds or at the time of birth, so careful prenatal follow-up is key.

Which professionals are involved? the gynecologist provides follow-up during pregnancy, the pediatrician evaluates the newborn, and the pediatric surgeon steps in when an affected structure needs to be corrected. Relying on this team makes it possible to plan ahead for the care each child may need.
